Step-by-step explanation:

for the candies r us website, the price of the candies is 30*6 then times 0.8=$144

Expand (2+x)^-3<br><br><br><br><br><br><br><br> ....
pentagon [3]

Answer:

1/(x^3 + 6x^2 + 12x + 8)

Step-by-step explanation:

The first thing we do is rationalize this expression. (2+x)^-3 is written as

1/(2+x)^3

Then from there we can foil out the denominator. It is easiest to foil (2+x)(2+x) first and then multiply that product by (2+x).

(2+x)(2+x) = 4 + 4x + x^2

(4+4x+x^2)(2+x) = 8+8x+2x^2+4x+4x^2+x^3.

Then we combine like terms and put them in order to get:

x^3 + 6x^2 + 12x + 8

And of course we can't forget that this was raised to the negative third power, so our answer is 1/(x^3 + 6x^2 + 12x + 8)

Let f(x) = -4x - 2 and g(x) = 5x - 6. Find f*g and state its domain.
elixir [45]

Answer:  The answer is (c) -20x^2+14x-12;\textup{ all real numbers.}

Step-by-step explanation:  Given that there are two functions f and g, defined by

f(x)=-4x-2,\\\\g(x)=5x-6.

We are to find f*g and also its domain.

(f*g)(x)\\\\=f(x)g(x)\\\\=(-4x-2)(5x-6)\\\\=-20x^2+24x-10x-12\\\\--20x^2+14x-12.

Also, its domain will be all real numbers, since the function f*g is defined at all 'x' in real numbers.

Thus, the correct option is

-20x^2+14x-12.

At eastwood middle school, 25% of the 60 sudents mrs. Wade teaches buy their lunches in the cafetria. How many students purchase
abruzzese [7]

Answer:

<u>15 students</u> purchase their lunches in the cafeteria.

Step-by-step explanation:

Given:

At eastwood middle school, 25% of the 60 students Mrs. Wade teaches buy their lunches in the cafeteria.

Now, to find the students purchase their lunches in the cafeteria.

Total students = 60.

Percent of students who buy lunches = 25%.

So, to get the number of students who buy their lunches in the cafeteria:

<u><em>25% of 60.</em></u>

=\frac{25}{100} \times 60

=0.25\times 60

=15.

Therefore, 15 students purchase their lunches in the cafeteria.
